Bronsted - Lowry acid in the given reaction is NH₄, as it gives H⁺ ion.
What is Bronsted - Lowry acid?According to the theory of Bronsted - Lowry, acids are those substances which gives H⁺ ion or proton in the aqueous medium.
Given chemical reaction is :
NH₄ + HPO₄²⁻ → NH₃ + H₂PO₄⁻
In the above reaction NH₄ is the Bronsted - Lowry acid as it gives H⁺ ion in the reaction and changes to NH₃ which is the conjugate base of NH₄. Whereas HPO₄²⁻ is the Bronsted - Lowry base as it accepts the H⁺ ion to form H₂PO₄⁻ which is the conjugate acid of it.
Hence, option (1) is correct, i.e. NH₄ is the Bronsted - Lowry acid.

find the location of flourine (F) on the periodic table what type of ion will fluoring form?
Answer:
VII'th group, negative ion
Explanation:
Usually fluorine is located in the seventh(VII) group as fluorine has 7 electrons in it's outer shell with chemical symbol "F"
Fluorine has 7 electrons in it's outer shell therefore, it needs one more electron to get the noble gas configuration. So more electrons means negative ion.

Sammy and Lisa measure the mass of 3 logs. They burn the logs in a campfire, then measure the ashes. They are surprised to find that the mass of the ashes is less than the mass of the logs. How can this be explained?
The mass was compressed into ashes when the fire burned so the mass of the product was less than the mass of the reactants.
The mass was lost because there was a chemical change.
Some of the mass of the logs was turned into smoke and gasses that escaped into the air.
Mass was destroyed in the heat of the campfire.
Explanation: Hope it helps <3
The law of conservation of mass states that, for any closed system, the mass of the system must remain constant.
So, in other words, mass cannot be created nor destroyed.
In a burning log, the initial mass of the wood and the ashes that are left behind after it burns are different, which would seem to violate the law of conservation of mass.
What is the reaction type between zinc chloride+ magnesim
Answer:
Redox reaction
Explanation:
Solid magnesium metal was added to aqueous zinc chloride. The zinc has a higher electronegativity than the magnesium and therefore attracts two electrons from magnesium, which gives magnesium a positive charge.

A buffer solution is made up of acetic acid (CH3COOH) and sodium acetate (NaCH3COO). The major equilibria in the buffer system are represented above. Which of the following equilibria could be used to support the claim that the addition of a small amount of NaOH to the buffer will result in only a very small change in pH?
CH3COOH (aq) + H2O → H3O+ (aq) + CH3COO- (aq)
CH3COO- (aq) + H2O → CH3COOH (aq) + OH-
2H2O (i) → H2O + OH-
a. CH3COOH(aq) + CH3COO- (aq) → CH3COO- (aq) + CH3COOH(aq).
b. CH3COOH(aq) + OH (aq) → 3CH3COO (aq) + H2O(1).
c. H3O+ (aq) + OH(aq) → 2H2O(1).
d. CH3COOH(aq) + H2O(1) → H30+ (aq) + CH3COO (aq).
The equilibria showing how the acetate buffer adjusts to addition of a small amount of NaOH is:
CH3COOH(aq) + H2O(1) → H30+ (aq) + CH3COO (aq)What is a buffer?A buffer is a solution which resists changes to its pH when small amounts of strong base or acid is added to it.
Buffers are made from solutions of weak acids and their salts or weak bases and their salts.
The equilibria showing how a buffer made from acetic acid and sodium acetate (NaCH3COO) adjusts to addition of a small amount of NaOH is as follows:
CH3COOH(aq) + H2O(1) → H30+ (aq) + CH3COO (aq)Addition of NaOH, a strong base will neutralize the hydronium ion, causing the acetic acid ionization equilibrium to shift to the right to produce more of the acetate ion, the conjugate base.

How many milliliters of a 2. 99 M solution of glucose, C6H12O6 , molar mass = 180. 155 g/mol , do you need to obtain 25. 0 g of glucose?
For 25.0 g of glucose, 138.9 ml of the 2.99 M glucose solution are needed.
The most common monosaccharide, or kind of carbohydrate, is often glucose.
Molar mass of glucose = 180.155 g/mol
Molarity of glucose = 2.99 M
Mass of glucose = 25.0 g
The formula for calculating the volume of a solution required to obtain a given mass of the solute is given by,
[tex]Volume of solution (V) =\frac{ Mass of solute (m) }{ Molar mass of solute (M)}* 1000[/tex]
Therefore, the volume of the 2.99 M glucose solution required to obtain 25.0 g of glucose is given by,
[tex]V = (\frac{25.0 }{ 180.155}) * 1000 V = 138.9 ml[/tex]
Hence, 138.9 ml of the 2.99 M glucose solution is required to obtain 25.0 g of glucose.

How many moles of C3H8 will be produced from 75 moles of CO2?C3H8 + 5 O2 → 3 CO2 + 4 H2O
25 moles of C3H8 will be produced from 75 moles of CO2.
Mole calculation
To find the value of moles of a product from the number of moles of a reactant, it is necessary to observe the stoichiometric ratio between them:
[tex]C_3H_8 + 5 O_2 = > 3 CO_2 + 4 H_2O[/tex]
Analyzing the reaction, it is possible to see that the stoichiometric ratio is 1:3, so we can perform the following expression:
C3H8 CO2
[tex]\frac{1mol}{xmol} =\frac{3mol}{75mol}[/tex]
[tex]x = 25mol[/tex]
So, 25 moles of C3H8 will be produced from 75 moles of CO2.
